Unicom 3G traffic SMS subscription failed? What should we do?

If 3G traffic packets cannot be displayed, the possible reasons are as follows: 1. This service does not open number attribution; 2 do not meet the conditions for handling; 3. The mobile phone is turned off and can only be processed when it is turned on normally; 4. The treatment method is wrong. If the instruction is sent incorrectly, please consult the manual customer service for specific instructions; 5. The system is busy. If there are too many people visiting the website at present, resulting in a busy system, you can try again later. If the above situation has not been solved, you can contact the local manual customer service to check the specific reasons.
